I am a visiting assistant professor in the Department of Mathematics at Texas A&M University, after receiving my Ph.D. at Temple University in 2004.

My research is focused on Algebraic Combinatorics, WZ-Algorithm, Combinatorial Games and Pattern Avoidance. Some of my work can be found in the list of publications below. Some can be found here: Chomp, Wythoff's Game and Peg Solitaire. There are also some results on Ternary Square-free words. I also worked on projects in computer science too.
